title: Updated analysis of an outpatient chemoimmunotherapy regimen for treating metastatic melanoma.
abstract: OBJECTIVE
  Aggressive inpatient chemoimmunotherapy protocols for metastatic melanoma have yielded encouraging response rates but have required lengthy hospitalizations. To reduce or eliminate the need for hospitalization, we have developed an outpatient chemoimmunotherapy regimen and assessed its efficacy and toxicity in 53 patients treated at the University of Washington Medical Center.
  
  
  METHODS
  Eligible patients with measurable metastatic melanoma received carmustine (150 mg/m2 every 6-8 weeks) and dacarbazine (660 mg/m2) and cisplatin (75 mg/m2) every 3 to 4 weeks in an infusion center plus tamoxifen (20 mg/day). Patients self-administered subcutaneous recombinant interleukin-2 (rIL-2) at 3 MIU/m2/day on days 3 to 9, and recombinant interferon alfa-2a (rIFN-alpha 2a) at 3 MIU on day 3 and at 5 MIU/m2/day on days 5, 7, and 9. Maintenance rIFN-alpha 2a was self-administered subcutaneously at 5 MIU/m2 tiw for 12 months after complete or stable partial response. Response and survival were assessed.
  
  
  RESULTS
  Fifty-three patients (median age = 49 years) have received 181 cycles. To date, there have been 10 complete responses (19%) lasting 2 to 28+ months and 12 partial responses (23%) lasting 2 to 11 months, for an overall response rate of 42% (95% confidence interval, 28%-55%). The median overall survival was 12 months. Grade 3/4 vomiting occurred in 32% of cycles, but hospitalization for supplemental intravenous fluids was required in only 11% of cycles for a median of 3 days. Grade 4 thrombocytopenia and neutropenia occurred in 9% and 8% of cycles, respectively. Grade 3 renal dysfunction occurred in only one cycle and was reversible.
  
  
  CONCLUSIONS
  A chemoimmunotherapy regimen for patients with metastatic melanoma has been defined that is well tolerated on an outpatient basis and is associated with a median survival comparable to that with aggressive inpatient chemoimmunotherapy regimens.
